Upon cach erin 8 is :i hrnnch erin 9, which et a rightnngle to the erin 8 projects forwardly end downwardly in the direction of the rotation of the shaft. in horizon tal sleeve i0, in which is jonrneled e shaft ll.

At the outer extremity of eeeh ol the nrrns 8 is n deviee for :tutonuitieully retelling und holding the lower end. et' the hlow-iron in alineineint with the mais ol the inold. This leviee is illustrated, on un enlznged seele, in Fig. ll), in whieh 5] e plete secured 'to the top or" the end o erin 8 hy ineens olt two serew-helts hissing down through elongated #curved holes 5i? in the plete, whifh permit the pls-te te he adjusted lenght linzrlly and laterally. 5" the plete is ne outer end et :t ,inw 53, the mouth of whi eh opens .wrdly to its line el' travel. 54 is e il ing "eeured en" one end, 55, hy a bolt rivet to the plate 5l and et its other end being eurved heelrwztrdly und resting partly eeross the mouth ol` the jew 53. "When the upper end of the l low-iron is pushed up into the hell-mouthed guide 38, the lower end ol' the blow-iron is et the saine time pushed sidehvv'ise against 'the spring 5%, whieh yields, per- 'n 'tting the iron to slip into the crotch oi the .l where is held hy the spring against lateral movement until the mentor lapplies sufiieient toreo to the iron to overeorne the spring. it will he understood that the plooing of the iron in operative position and the removal olthe iron is ulwztys eeeoinplished when the nieldhnlves ure thrown into open position. i

' Bose 1 end eohnnn 2 are hollow ond forni a reservoir for compressed nir furnished hy an pump, the plunger ol which, 56, recipro- 40 .entes in the upper end of the column 2 and is actuated by rod 57, eonneeted with eeeentric-strop 58 on eeeentrie 59 on coun ter-shaft 50, driven herein :liter d eseribed. Plunger 56 is provided with :i eheelevalve 61, opening inwz'trdly, and in the borrel of the eir-purnp is 'fixed :mother cheek-vulve 62, which also opens inwardly, both vulves being held normail); closed hy springs1 s-shown.

The shalt l is hello-W, und nt its lower end the hollow is in eoinmunieotion with the com pressed-nir chamber in "the hase oit the Inoehine through the elongated hub 6, 'formed on top of the hose ol' the ineehino. The arms hollow, und the hollow of euch. of these urine is in eonnnunieation with the hollow of the shzrl't.A ln eeeh el the arms 33 is e piston.'- velve 63, recipromrtngv in valve-oase 64, let into the erin 33. ln opposite sides of the valve-ceso are smell holes. A circumfero entiel channel or groove 66 is formed on the valve.' This ehennelorgroove maybe moved ,int-o eoineidenee with lthe holes 65, so that there will he en. uninterrupted stir-passage tlnoneh'the velve and valve-cese. A spring itl? holds the valve eleveted so that the eirpassage is normally vlosed. Pussing through the top of the vulve-euse o4 is :tu udjuslingscrew (lo, the lower end ol which eonturts with the top ol vulve 65%. rthis :uljustiugscrew is supported in u tlneded hole in n bent lever of), lulerumed, es ut 7l), upon u bracket 7l, formed upon the urxu 32%. lhe opposite end ,of the lever esrries u lroller 72, which rides upon the under side ol' segmental rimY 73, ndjustably secured to the underside of 'l'iietioix-wlieel 32.'

ln blowing' gloss in molds it is necessary that the pref-sure ol' the compressed oir he regulated ueeordingr to the elmrurter und size oll the nrtirle to he blown und the degree ol lluidity ol' the hot gloss. ll is also soulet'iine's desiruhle that this pressure he varied during the blowing ol.V eneh single nrtiele. l provide 'for this adjustment und vuriution of pressure :1s `lollows: The segmented ring' 73 is supported hy ineens ol pins 74, secured nt their lower ends to the ring' und pnssi'ng' up tl'irough holes in the frirtion--dislt 32. The pins 74 have hoods between which und the top oi the lrletion-dish ure interposed coiled springs 75, which forni :tu elustie support 'l'or the ring. nssingdown und threuded through the friction-dish 32 are three ndi listing-screws 76, spaced eport, :ts shown, their lower ends abuttingr against the top'o'l theI ring` Til. By ineens ol' uheso srrews the ring; 725 or either end or the nriddlo thereo'l" muy he ruised 'or lowered, :as muy he desired. Slnee the swing ol. the levers 69 und the throw ol the vulves depend upon the position ol the segmental ring 73,011 which the rollers 72 lruvel, it will he seen that the extent oln the opening of' the oir-valve o3 `und the eonsequex'it degree ol :Lirpressure inthe blow-irons are regulated und eontrolled through the vertical or angular udjustinent ol the seg-mental ring, neeonlplished by means olthe ndjusting-serews 76.

The shnl'ts 37 have therethrough und in communication 'with the hollow oi' nrnls 33 two transverse Cross-passages 37, whieh ut their intersmztion ure in eounuun'iention with axial nirpussages 37". lletween the lower end of the shalt 37 und the top ol" the bellmouthed guide 38 is ehunped n gushet 77, having o een tral,perlorution lor the reception oi the upper end ol the blow-iron. lt will be seen that when the blowiron is in plztee and. when the vulve 63 is open there is new un uninterrupted passage troni the eon'ipressed-air ohmnher through the blow-'iron to the llosh.

Secured to the eolunin 2, neer its top, is o bracket 78, upon which is mounted an eleetric motor 79. Upon the shaft of the motor is e pinion 80, whieh engages e trein of which drive the counter-shalt 60.
